Mineral Resources (MinRes) has delivered a record first half for its mining services division, driven by strong external demand and the continued ramp-up of its Onslow Iron project.

The division, led by subsidiary CSI Mining Services (CSI), recorded production volumes of 166 million tonnes (Mt) and earnings before interest, taxes, depreciation and amortisation (EBITDA) of $488 million in the first half of the 2025-26 financial year (FY26) – up 29 per cent on the prior corresponding period.

The result reinforces MinRes’ position as a leading integrated mining services provider, with CSI now one of the largest crushing contractors globally. The business operates 28 installed plants with a combined capacity of 167 million tonnes per annum (Mtpa).

MinRes chief executive mining services Mike Grey said the division had a history of bringing crushing and processing innovations to the market.

“At its core, CSI provides build-own-operate crushing and screening plants and mobile crushing equipment for some of the world’s largest mining companies across commodities such as iron ore, lithium and gold,” Grey said.

“Our focus has always remained on delivering efficient solutions to crush and process ore as safely and quickly as possible, which delivers real value to our clients. This has never been more evident than during the first half of FY26, when we delivered an exceptional result.

“CSI’s continued growth is testament to the quality people within our division and their ability to take complex situations and projects, distil a solution and work with other MinRes divisions to deliver them on time and on budget.”

A major contributor to the half-year result has been the performance of MinRes’ NextGen modular crushers at Onslow Iron in the West Pilbara. Three units, representing up to 45Mtpa of installed capacity, have supported the successful ramp-up to nameplate capacity of 35Mtpa.

CSI operates across Western Australia, the Northern Territory and Queensland, supporting both MinRes-owned projects and external clients with pit-to-ship solutions.
